Abstract:
:Chromatin structure and nucleohistone pattern were investigated histochemically in the neutrophils of 11 schizophrenics and 16 healthy controls. Compared to controls, all schizophrenic parents prior to medication showed a distinctly different histochemical pattern consisting of increased concentration and abnormal distribution of nucleohistones. This pattern has been attributed to an increase of arginine-rich histones in schizophrenics. Pimozide administration exerted a normalizing effect on the nucleohistone distribution pattern. These findings further support our view that genomic expression abnormalities may be related to schizophrenic illness.
